Objectivism holds that there is one true morality binding upon all of us.

客观主义的观点是：存在一条道德真理对我们所有人都具有约束力。

If moral relativism is true, morality can be regarded as a tool, and we can think about what we'd like that tool to do for us and revise morality accordingly.

假设道德相对主义是对的，道德观就可以被当成一个工具，我们可以想想用这个工具帮助我们做什么，以及如何相应地改进道德。

Relativism does tell us, however, that we are mistaken when we think we are in possession of the one true morality.
